I'm not sure, but I think its the 88-89 cam, which is 207/213 duration, .415"/.430" lift, and 117 lobe.

Scoggin Dickey is selling take-off ZZ4 cams for $100. Much bigger than the TPI cam.

You have a roller engine? I'd find an LT1 cam from a 4th genner. They have about the same duration, but the lift is higher. Or put an ad in the classifieds here, I'm sure someone has one they've taken out of their car.

I think I have one. I have an 89 vette 350 block with stock roller cam. I will be changing it out for a new one in a few weeks. I am not 100% sure it is the one you are looking for but it is definitely an 89' vette engine with roller cam.

Re: Stock cam specs
Would anyone have a source and part number? Looking for a stock replacement for an 89 IROC TPI roller (or maybe for a Corvette) as long as the computer will work with it. Will not be racing it
